UNITED STATES PATENT QFFICE.

JOHN SHERRY, OF BROOKLYN, NEW YORK.

PADDLE- WHEEL.

SPECIFICATION forming part of Letters Patent No. 225,493, dated March 16,, 1880. Application filed September 24, 1879 To all whom it may concern:

Be it known that I, JOHN SHERRY, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Paddle-Wheels, the construction and operation of which will be fully understood from the following description, reference being had to the accompanying drawings, forming a part of this specification. I

The object of this invention is to construct a paddle-wheel whose buckets or arms will not beat upon the water in entering, and which shall not raise or lift dead water in its revolution, thereby preventing to a great extent the tremor or shaking of the vessel; and from the peculiar shape of the buckets the Wheel may be given a greater speed than that of an ordinary paddle-wheel of equal diameter; and the buckets of the said wheel being made of metal in hollow form, of diamond shape, great strength is given to them, as well as giving buoyancy to the wheel, which is of valuable service in giving life to the vessel when running; and, furthermore, in having the buckets radial and of diamond shape, forming an extension of the arms or'spokes, it makes the same invaluable as an ice-breaker, as it will climb the cake, and, bearing directly down upon it, will cause the same to crush or sink.

Figure 1 represents a side view. Fig.2 is a front or face view of one of the buckets detached. Fig. 3 is a sectional view of the same through the line 00 m. Fig. 4 is afront or face view of a modified form of bucket. Fig. 5 is a sectional view of the same through the line 1/ y- Similar letters of reference indicate corre sponding parts.

In the case here presented the buckets A are preferably made in sections, of boilerplate, whose flanges B B are bolted or riveted together, so as to make good Water-tight joints. The said sections, when set together, form a ho]- buckets of wood, in which case I adhere tothe original form as above described; but owing to the buoyant properties of the wood I make them solid, as shown in the drawings, (see Figs. 4 and 5,) and to protect their edges I sheath them with metal D.

It will thus be seen that in making the buckets of diamond shape to a greater or lesser degree they will enter the water without striking dead thereon, and will leave the same without producing or lifting dead water, and that by staggering the spokes and buckets their peculiar shape will cause a series of contorted currents as the wheel revolves, thereby giving the wheel a good and sufficient hold on the Water.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A paddlewheel having hollow air-tight diamond-shaped buckets set radially to the hub, for the use and purpose substantially as shown and described.

2. A paddle-wheel having diamond-shaped Wooden buckets sheathed with metal and set on the same radial line with its spokes, the same being constructed, arranged, and operating in the manner and for the use and purpose described.
